Analysis stuck with several bogus functions

[xusheng6]

While analyzing kernel32.dll_.zip, the analysis takes 550+ seconds to finish. I found that most of the time are wasted in analyzing a few bogus functions. They are not real functions, but they happen to be possible to disassemble. And the analysis seems to get into a loop on some of them, though eventually the analysis correctly bails out when the function analysis time exceeds the limit. We should see if we can fix the analysis loop and bail out sooner
